If you are trying to understand the DA vs DR comparison or looking for a direct moz domain authority vs ahrefs domain rating breakdown, the short answer comes down to third-party measurement models. In today’s SEO landscape, understanding how different platforms evaluate DA rankings and overall website authority is crucial.
Two of the most important tools used to measure this are Domain Rating (DR) from Ahrefs and Domain Authority (DA) from Moz. Although neither of them is an official Google ranking factor, both are useful in determining how strong a website’s backlink profile is.
In this article we’ll explain what Domain Rating and Domain Authority actually are, why they matter for your SEO efforts, and how to make the best of them.
What is Domain Rating (DR)?
Ahrefs developed a metric called Domain Rating to measure how strong a website's backlink profile is on a scale of 0-100.
The more links you get from authoritative websites, the more it shows search engines that your site is trustworthy, boosting your visibility over time. Your site's DR is calculated based on two main things: the number of backlinks getting pointing to your site and their overall authority. It’s not just a numbers game, because getting a link from an authoritative, niche-relevant website will take you a lot farther than a link from an irrelevant site.
That’s why one strong link can outweigh dozens of weaker ones. As your score increases, it gets harder to improve. For example, going from a 20 to a 30 is much easier than going from an 80 to a 90.
Ahrefs also offers a free DR checker tool that lets you see your website’s DR alongside other basic metrics like the total number of backlinks and referring domains.
What is Domain Authority (DA)? How Moz Calculates it
Domain Authority (DA) is a metric created by Moz that predicts how well a website will rank on search engine result pages (SERPs).
Unlike DR, which mainly looks at backlinks, DA factors in a broader mix of elements, including linking root domains, total link counts, and machine-learning factors. In other words, DA gives you a bigger picture of your website’s general strength on a scale of 1 to 100.
Key Differences Between DR and DA
The main difference between Domain Rating (DR) and Domain Authority (DA) is what they focus on. DR analyzes your site’s backlink profile quality and quantity, while DA looks at a broader slew of SEO metrics to analyze your site’s general ranking potential.
Because they are built by different developers using independent data models, the same website can get very different scores in each system. DR tends to update quickly when a new backlink is added or removed, while DA typically shifts slower during larger periodic updates.
Why Your DR and DA Don't Always Match
If you check your website on both platforms, you'll often notice a mismatch. Your DR might be 45 while your DA sits at 28. Why does this happen?
The Spam Inflation Trap
If a site builds spammy links, Moz's spam scoring model often penalizes the overall score quickly, dropping DA. Meanwhile, Ahrefs' DR might stay artificially inflated until those links are fully discounted by its specific math.
The Brand-New Domain Anomaly
A brand-new website with just three mega-authoritative links (like a mention in TechCrunch) will see its DR skyrocket instantly because Ahrefs heavily rewards elite referring domains. However, Moz's DA will stay low because DA factors in historical age and overall breadth across the web.
Why Both Metrics Matter in SEO
Both DR and DA are valuable for measuring site health, but pairing them paints the full picture. For example, if you have a high DR but a low DA, it usually means your site has great backlinks paired with poor user experience or underlying technical layout issues.
When working with clients, tracking changes in both metrics helps monitor progress over time, run competitive analyses, and measure overall Return on Investment (ROI).
Strategies to Boost Your DR and DA
Because DA focuses heavily on broader link signals and DR is driven by referring domains, improving both comes down to earning trustworthy references through long-term execution:
Quality Backlinks
Focus on acquiring high-quality backlinks from reputable sites as part of a broader link building for SEO strategy to boost both DR and DA.
Content Quality
High-quality, engaging content attracts natural backlinks and is favored by both Ahrefs and Moz algorithms.
SEO Best Practices
Adhere to SEO best practices such as optimizing site structure, increasing site speed, and ensuring mobile-friendliness.
Regular Audits and Updates
Conduct regular SEO audits to identify and rectify issues that could be impacting your site’s performance. Updating outdated content, fixing broken links, and removing toxic backlinks can significantly improve both DR and DA
Social Signals
While not direct ranking factors for DR and DA, social signals such as shares, likes, and comments can increase the visibility of your content and lead to more natural backlinks. Encourage engagement by promoting your content across social media platforms.
Diverse Link Profile
Aim to diversify your backlink profile by securing links from various domains and using different types of links, such as contextual links within body content, footer links, and links from different geographical regions.
User Experience (UX)
Enhancing the user experience on your website can indirectly impact DR and DA by reducing bounce rates and increasing page views and time on site. Focus on creating a responsive design, intuitive navigation, and fast-loading pages to keep users engaged.
Case Study: Increasing Domain Rating from 11 to 60
To illustrate how a Domain Rating can increase over time, let’s look at a live case study from one of our own clients.
When we started working together in April, their website had a DR of 11.
To turn that around, we focused on strengthening the backlink profile, boosting keyword rankings, and generating organic traffic using a mix of competitor research, broken link building, digital PR, and skyscraper-style content.
These efforts brought in strong backlinks from other websites and slowly improved the site’s authority. And so, in the span of six months, the DR jumped from 11 to 60.
To go deeper into these strategies, you can look at our other case study on scaling a social media ads tool from DR 11 to 60.
Frequently Asked Questions
What is the difference between Domain Rating (DR) and Domain Authority (DA)?
Domain Rating (DR) is developed by Ahrefs and measures the strength of a website's backlink profile on a scale of 0 to 100. Domain Authority (DA) is developed by Moz and predicts a website's overall ranking potential using a broader mix of link counts, linking root domains, and machine-learning factors.
Why do my Ahrefs DR and Moz DA scores not match?
DR and DA are calculated using completely different proprietary data models and crawlers. Ahrefs updates its metrics quickly when backlinks are added or removed, while DA typically shifts slower during periodic Moz index updates. Additionally, factors like spam inflation or brand-new domain age weighting cause discrepancies between the two scores.
Are DR and DA official Google ranking factors?
No. Neither Domain Rating nor Domain Authority are official Google ranking factors. Google evaluates websites using thousands of individual signals, page-level quality, and core web vitals. DR and DA are simply third-party benchmark metrics used by SEO professionals to measure backlink strength and competitive progress.
Which metric should I trust more for SEO?
Neither metric should be trusted blindly, but they serve different purposes. If you want to evaluate the sheer power and quality of a site's backlink profile, Ahrefs' DR is generally preferred. If you want a broader predictive baseline of general search visibility across diverse ranking factors, Moz's DA is a helpful complementary indicator.
Final Thoughts on Domain Rating vs Domain Authority
Choosing between Domain Rating and Domain Authority depends on what you want to evaluate: backlink profile quality or general ranking potential. Neither metric is a direct Google ranking factor, but they are essential tools for measuring competitive performance.
Improving your scores on both platforms is a good sign that you’re on the right path, but the real focus should be on developing long-term SEO growth. That is something our team at LinkyJuice specializes in helping brands achieve.
